Specification of Letters Patent.

To all whom it may concern:

citizen of the United States of America,

residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Roller- Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to roller bearings of the type adapted to carry both radial and end thrust loads, and has particular. reference-first, to the means for retaining the rollers so as to be readily engageable with and disengageable from their cooperating race members; further, in the means for holding said rollers in proper alinement; and further, in various specific features of construction as-hereinafter set forth.

In the drawings: Figure 1 is a perspective view of the several parts of the roller bearing detached; Fig. 2 is a central longi-" tudinal section through the assembled bearing; Fig. 3 is a cross section on line w-w Fig. 2; and Fig. l is a cross section on line g -g Fig. 2. r

It is the primary object of the invention to obtain a construction of combined radial and end thrust load carrying roller bearing, in which all contacting surfaces have the same ratio of speed. This having enlarged heads in cooperation with a conicalrracemember having a transversely-extending end thrust surface adapted to bear against the enlarged heads of the rollers in the line of projection of the conical surfaces thereof. The ratio of speed is therefore the same between the end thrust load carrying surfaces, so thatfriction is reduced to the minimum. It is essential, however, to maintain a proper of the rollers; for which purpose I have provided a cage 'or roller holder of novel construction. 1

As shown, A is the outer race member,- B the inner race member, both of which are of conical form butof diflerent tapers, so as to provide a space therebetween for a series of conical rollers C. One of the race members-such as the member B'-is provided I obtain by the with a transversely extending end thrust bearing surface of pro]ection of the conical surface E and groove F- separating said surfaces. Each of the rollers C is provided with an enlarged Patented Oct. 10., 1916. Application filed June 28, 1913. Serial 1%. 776,274.

D, which crosses the plane head G, which has a spherical end face H for contacting with the face D of the race member B. The surfaces H and D are so fashioned. and are at such an angular relation to each other that the line of contact will be in the projection of the conical surfaces of said rollers and race member B, as 1 above stated. The rollers are spaced and held in proper alinement by a cage member Llwhich is so constructed as to fit between the race members B and A, out of contact therewith, and at the same time to form receivlng sockets for the rollers. I prefer- I ably form this member I as a die casting,

having the central conical recess J for receiving the inner race member B, and a series of conical recesses K for receiving the rollers C. These recesses intersect the outer and inner facesof the cage, so as to form a series of oppositely concaved spacer members L, which at their ends are tied together by continuous rings M and N. The ring M, which is at the small end of the cage, is located beyond the ends of the rollers, while the rlng N, at the large end of the cage, is laterally ofiset or of larger diameter so as to clear the sockets K and permit of the insertion of the rollers therein. The sockets K are also provided with enlarged ends K for receiving the heads G of the rollers, and the with a slight clearance space from their respective sockets, which permits freedom for rolllng.

To hold the rollers in engagement with y the cage,'l preferably provide a retainer 0,

which, as shown, is a sheet metal ring extending'over the ends of the cage and rollers, and having a flange P spun inward j about the oifset in the cage to lock the retainer in position. When thus arranged, the cagewith the rollers therein may be engaged or disengaged with the race members A and B, suflicient clearance being provided between the retainer'O and the ends of the rollersto allow the latter to move outward, so that the enlarged heads G may pass the large end of the cone E and into engagement with the groove F.

What I claim as my invention is:

1. A roller bearing, comprising concentrically arranged inner and outer race members, a series of rollers therebetween, and an annular cage filling the space between said race members with a slight clearance from the surfaces thereof, said cage having a series of recesses therein, open at one end for the reception of the respective rollers, said recesses intersecting the inner and outer surfaces of the cage to provide clearance for the portions of the rollers contactin race members, and imperforate rings at the opposite ends of said cage member for holding the portions between said rollers in fixed relation.

2. A roller bearing, comprising inner and outer concentrically arranged conical race -members, one of said members being provided with a transversely arranged end thrust bearing surface, a series of conical rollers interposed between said race members and provided with enlarged ends having spherical surfaces contacting with said transversely arranged end thrust surface in line with the projection of the contacting conical surfaces of said rollers and race member, and a cage for retaining said rollers formedof a die casting fitting with a slight clearance between said inner and outer race members and having a series of conical recesses therein for receiving the respective rollers, said recesses being enlarged at one end tov receive'the enlarged heads of said rollers and intersecting the inner and outer surfaces of said cage to provide clearance for the portions of said rollers contacting with said race members. 7

3. A roller bearing, comprising inner and outer concentrically arranged conical race members, a series of conical rollers interposed therebetween and provided with enlarged heads with spherical end thrust bearing surfaces, a transversely extending end thrust surface on one of said race members contacting with said rollers in line with the projection of the contacting conical surfaces of said rollers and race member, a cage for said rollers comprising a die casting completely filling the space between said'race members and rollers, with a slight clearance from the surfaces thereof, the recesses for receiving the individual rollers intersecting the inner and outer surfaces on said cage, and a laterally projecting ring at the en larged end of said cage for uniting the spacing portions between said rollers.
